This series was discontinued in 1982 and superseded by the Report of Investigation Series. It contains reports of research by DGGS personnel. Its objective was to make information available to the public as soon as possible, and therefore reports of this series were not subjected to rigorous critical review and formal editing and did not use professional cartographic services.

This series includes reports from 1912 through 1958 published by the Territorial Department of Mines, and from 1959 through 1982 published by DGGS's predecessor agencies. These reports describe annual mining activity in Alaska and summarize statistics on exploration and production of Alaska minerals. The later reports also highlight the activities of DGGS and its legislatively mandated responsibilities. After 1982, the minerals summaries were published in the Special Report series. Beginning in 2000, the Annual Report series was reactivated to produce reports highlighting the division's history, activities, accomplishments, projects, and publications produced during the year.

Reports of this series show sample localities and chemical analyses of stream sediment and rock samples. The series was discontinued in 1973, and information of this type is currently included in the Professional Report and Report of Investigation series.

This series includes "field trip" guides that contain general and technical information to help visitors understand the geologic conditions they observe along some of the major transportation corridors of Alaska.

Reports of this series contain analytical and interpretive data resulting from testing by third parties on material borrowed from sample materials housed at the Alaska Geologic Materials Center. These reports are produced by the third party agency or company that conducted the sampling and analysis. The reports have not undergone technical peer review and should not be used or cited as reviewed data. DGGS may not have access to and thus cannot provide the digital forms of all of this data.

This category includes geophysical maps, contractors' geophysical reports, and small interpretive reports on geophysical modeling. It does not include reports with DGGS staff interpretations of the geology based upon the geophysical data, which are released either as PIR or RI reports.

Laboratory Notes and Reports were published from 1968 to 1973 as technical summaries of methods and procedures used for chemical analyses in the DGGS assay laboratory. The reports provide information about the reliability and limitations of the results of chemical analyses.

This series consists of reports difficult to classify in any other category, including layered reports consisting of previously published, reviewed, and edited data such as geological and geophysical maps, technical letters, or summary reports of meetings, symposia, and the like. These reports may or may not have been reviewed for technical merit.

This series includes all issues of Alaska GeoSurvey News released by DGGS. The newsletter, which was reestablished in 1997 after a lengthy hiatus, was designed as a less formal avenue to present progress reports, highlight DGGS projects, and provide timely summaries of geologic information. Each issue includes a listing of reports and maps that have been published since the previous issue.

The objective of this series, published from 1983 through 1999, was to make project and field data available to the public as soon as possible. PDFs were not reviewed or edited. This series has been replaced by the RDF series.

This category is intended for the timely release of maps and reports with preliminary interpretation of geology or analytical data. It includes reports by DGGS staff, scientists from other organizations, and contractor reports containing technical interpretations of analytical data. Maps and reports have been reviewed by one or two people for technical content.

Please Note: Maps, figures and text available through this page have not necessarily undergone technical peer review and should not be used or cited as reviewed data. Future reviewed publications incorporating these data may or may not change the interpretations presented.

Professional Reports communicate new data and original ideas to other earth scientists. Two characteristics separate the PRs from other series: A PR is the completed product of original research and analysis, and PRs use professional cartography and undergo rigorous peer review, editing, and revision to ensure accuracy.

Until 1999, reports in this series were usually written by DGGS staff from field notes and observations. The objective of this series was to provide information to the public as quickly as possible, and therefore editing and review were limited. Since that time, this series has been the final product of most projects; it now contains final reports of research of topical problems or specific map areas by DGGS or academic or industry researchers. The category includes geophysical reports that contain geologic interpretations of the geophysical data. The reports now receive two technical reviews as well as technical editing.

Reports in this series summarize or compile existing information on matters of current relevance related to earth science in Alaska. These publications are written for the general public, are given both internal and external review, and are edited thoroughly. This series includes the annual report on Alaska's mineral industry.
